// cleared on the Gecko thread when the pending call happens on the UI

//
// 1) happens through OnDetach, which first notifies the UI
// thread through Destroy; Destroy then calls DisposeNative, which
// finally disposes the native instance back on the Gecko thread. Using
// Destroy to indirectly call DisposeNative here also solves 5), by

//
// 2) and 3) are solved by clearing mWindow, which signals to the
// pending event that we had shut down. In that case the event bails
// and does not touch mWindow.
//
// 4) happens through DisposeNative directly. OnDetach is not
// called.
//
// 6) is solved by keeping a destroyed flag in the Java NPZC instance,
// and only make a pending call if the destroyed flag is not set.
//
// 7) is solved by taking a lock whenever mWindow is modified on the
// Gecko thread or accessed on the UI thread. That way, we don't
